Catalogue 5 - STAUFF Quick Release Couplings

www.stauff.com/5/en/#145 145 FG Catalogue 5 § Edition 03/2024 STAUFF Screw-to-Connect Couplings Series FG § Carbon Steel Product Description Features Flat Face screw-to-connect couplings of the FG Series from STAUFF consist of a female body with a screw sleeve and a male tip with external thread. The Series is developed for particularly heavy-duty applications for connecting hydraulic lines up to DN31,5 (1 1/4"). Coupling (screwing) and uncoupling (unscrewing) of the two halves is safe and very easy. After the connection is complete, all internal components have minimal play or clearance, which significantly reduces the risk of material fatigue. Another advantage is that the risk of permanent indentation, so-called "brinelling", on the surface of the male tip is eliminated, which can occur with push-to-connect couplings in similar extreme applications. The proven design is suitable for use in heavy construction and transport equipment, oil and gas platforms, blow out preventer (BOP) systems and gensets. Other applications include heavy lifting equipment, loaders/trai- lers, Drilling rigs, Piling Rigs and other demanding hydraulic applications. The FG Series is available in nominal sizes 10, 12, 16, 19, 25, 31,5 (3/8" - 1 1/4"). The nominal sizes 12, 16, 19 and 25 are certified according to API-16D (American Petroleum Institute) and EUB Directive 036 by LRQA (Lloyd‘s Register): Fire resistance test at 345 bar (5000 PSI) and a flametempera- ture of 700° C (1300° F). § Flat Face § Coupling made from carbon steel with Zinc/Nickel surface coating § Sealing’s made from NBR (Buna-N®), PTFE, PU, POM § Heavy duty internal components § Male tip or female can be connected up to 250 bar (3626 PSI) by hand or easy with tool § Tested acc. API-16D and acc. EUB Directive 036 (nominal sizes 12, 16, 19, 25) Applications Construction Machinery Hydraulic trailers Hydraulic tippers Lifting Equipment Top Features Zinc/Nickel coating Designed for secure connection Vibration resistant Oil and gas industry (onshore) Connect Under pressure § Feature: Green O-Ring External O-ring as a safety feature to indicate the complete/correct connection of the male tip and female body (the O-ring must be covered by the sleeve of the female body)
